EtherNet/IP to HART Multi-drop Gateway

5207-DFNT-HART

The ProLinx EtherNet/IP to HART Multi-drop gateways create a powerful connection between devices on an EtherNet/IP network and HART Multi-drop devices. This stand-alone DIN-rail mounted protocol gateway provides one Ethernet port and four HART Multidrop channels.

The EtherNet/IP protocol driver supports the Explicit Messaging implementation of the protocol. User-configurable as both a Client and a Server, the EtherNet/IP port is a very powerful data transfer tool.

The HART protocol driver works as a Master on four (HART) or eight channels (HART2 not available on certain configurations) per interface card, depending on implementation. Each channel is individually configurable.

Application

The DFNT-HART modules are the ideal solution for the many applications where EtherNet/IP connectivity can be used to integrate HART Multi-drop devices into a system. The EtherNet/IP gateway is a powerful module designed with both Client and Server support, enabling easy connection to Rockwell Automation PLCs (CLX, SLC, PLC, CPLX, and similar devices). In combination with the HART Multi-drop device support, the module provides a very powerful interface to the over two million HART devices which are in use in the industrial marketplace today. Applications for the module are found in most industries, especially Manufacturing, Oil and Gas, Electrical Power and Food Processing.

Internal Database

The ProLinx module contains an internal database that consists of areas for application data, status information, and configuration information.

The internal database is shared between all ports on the module and is used as a conduit to pass information from a device on one network to one or more devices on another network.

Application Data Area

The data area is used to store and retrieve data by the protocol drivers and for data exchange between protocols. The database is used as a source for write commands to remote devices and holds data collected from the remote devices. Commands defined in the configuration file (stored in the configuration data area) control how the data is to be handled in the database.

Status Data Area

This area is used to store error codes, counters, and port status information for each port.

Configuration Data Area

This area contains module configuration information such as port configuration, network information, and command configuration. This configuration file is downloaded to, or uploaded from, this area.

DFNT Protocol Specification

The EtherNet/IP protocol driver supports the Explicit Messaging implementation of the protocol. User-configurable as both a Client and a Server, the EtherNet/IP port is a very powerful data transfer tool.

Protocol Specifications

The EtherNet/IP protocol is one of the primary connectivity tools to the different Rockwell Automation platforms. The Explicit Messaging aspect of the protocol (only) has been implemented in the ProLinx units to provide the data transfer link between the ProLinx units and the Rockwell Automation hardware.

General Protocol Information

Messaging

PCCC on CIPExplicit Messaging supported

Miscellaneous

125 word read and write data lengthsFloating point data supported

EtherNet/IP Server Specifications

In Server mode, the module accepts commands from one or more clients to read/write data stored in the module's internal registers.

EtherNet/IP Server Specifications

Connections

Five independent TCP server sockets permit remote clients to interact with all data contained in the module.

In Client mode, the module controls the read/write data transfer between the gateway and other EtherNet/IP devices. Data transfer can be initiated and executed without any ladder programming being required in the Rockwell Automation hardware.

EtherNet/IP Client Specifications

General

One client

Command List

Support for 100 commands, each configurable for command, IP address, register to/from addressing and word/bit count.

Polling of command list

User configurable polling of commands, including disabled, continuous and on change of data (write only).

HART Protocol Specification

The HART protocol driver works as a Master on four (HART) or eight channels (HART2 not available on certain configurations) per interface card, depending on implementation. Each channel is individually configurable.

Protocol Specifications

The HART Master Protocol exists in 4 channel implementations with HART2 allowing 8 channels. This driver can be configured on an individual channel basis to operate as a HART Master Station and supports all the available HART commands including Universal, Common Practice and Device Specific Commands. Each HART channel is independently configured to interface with the internal database in the module.

The auto-poll mode allows the module to automatically collect data from each HART instrument on the channel and store the data in the module's database without the use of user commands. The module automatically generates HART commands 0, 3, 13, 14 and 15.
